Hi @RivkyH8,

Thank you for reaching out to Constant Contact's API Support.

In order to fully troubleshoot we would need some information that is best kept off of a public forum. Would you please send us an email at webservices@constantcontact.com with your API Key and the endpoint that you are trying to use along with any JSON data that you are sending if applicable?
